Presents a criminalistics laboratory experiment of benzidine rearrangement and the detection of trace quantities of blood which does not utilize carcinogens. (SL)

Stefan's law is demonstrated by measuring the temperature of the tungsten filament of an electric light bulb and plotting a log-log graph of temperature against power dissipation. (MLH)

Describes an experiment which allows students to observe the four oxidation states of vanadium obtained in aqueous solution. (SL)

Describes an experimental arrangement which provides a simple introduction to holographic interferometry. (SL)

Presents simple and inexpensive demonstrations of properties of metallic glasses. (SL)

Reviews the Hafele-Keating experiment on relativistic changes in eastward and westward moving cesium atomic clocks. Recommends the use of the Sagnac effect to remove the east-west time asymmetry and of the general-relativistic effect to elucidate the clock-rate changes. (CC)

Describes an experimental method of measuring the molecular weight and subunit corporation of an oligomeric protein. (SL)

Describes a geology laboratory exercise involving weathering and topographic maps which allows students to put knowledge to practical application. (SL)

Describes a simple chemistry laboratory experiment which allows students to calculate thermodynamic values. (SL)

Describes a laboratory kinetic experiment which demonstrates the important phenomenon of general catalysis by bases and/or acids. (SL)

Analyzes the role of experiments in science teaching, and applies this analysis to the teaching of Millikan's experiment in physics. Critically examines an article written by T. J. Harvey entitled Millikan made easy'' which was previously published in The School Science Review. (JR)

Describes a chemical experiment which illustrates the Beckman rearrangement and ring opening reactions. (SL)

Describes an open-ended chemistry laboratory project for organic chemistry laboratories. (SL)
